Editors' Choice: Aero Road Bikes

Why Aerodynamics Matter

7 / 8

About our wind-tunnel test: We typically prefer to test bikes on the road, experiencing them the same way you will. But there are some qualities we can’t evaluate on the road, including aerodynamics. To test the veracity of the claims these five manufacturers make about their aero road bikes, we took six of them to the A2 Wind Tunnel in Mooresville, North Carolina. In addition to testing the five finalists in the aero road-bike category, we also tested our 2012 Editors’ Choice best race bike, the Specialized S-Works Tarmac SL4, to see how it compared.
